To all whom 'Lt may concern: v

Be it known that I, LVAH D. HADSEL, States, and a resident otPhiladelphia, in the county of l?hila delphia, State of Pennsylvania,have invented a. new and useful Improvement in Slack-Cable Excavators,ot lwhich the tol lowing is a specification.

This invention relates to distant power excavators of that-type in whichthe scoop or ':onreyer l is movable along or upon a cable Way, composedof one or more cables, the cable may being 'so arranged as to be adaptedto be slacltened to permit the scoop to engage the earth Jfor diggingand filling, and to be tightened to cause the conveyer tobe operatedtree from the earth during transportation in either direction.

yThe invention comprises certain details of construction hereinafterfully described and claimed, and illustrated in thefaccompanyingdrawings, in Wl1`1ch- F'gure l is a diagrammatic plan View representingthe general arrangement of the cable Way and supporting and operatingdevices there or; Fig. 2 is an elevation corresponding to AFi l; Fig. 3is a View ot the turntable support, showing the scoop in the dumpingposition; Fig. 3a is a detail ot the 'adjusting mechanism; Fig: l is aplan View il in* e z .sinne d ioltaeinn t leniaractei at n i Allies :inLiliid Y ip c. darin giifltaiicntr ,t antivirale.'

Theturntable may rotate automatically to compensate `for such lateraladjustment. of the Way, or itmay be rotated positively by any suitablepower devices,but Iprefer to gear the Winch 18 to the turntable asindicated at 19, to cause simultaneous lateral movements thereof.

The conyeyer is illustrated as comprising a carriage 20 having Wheels 2lrolling upon theA cable way 12 and a scoop 22 pivotally connected bylinks '23 to the rear end ot the carriage. The scoop has one or moredratt arms 24 to which the main draft cable 25 is attached,the samebeing operated 'from any suit-ably located powerdrum 25.
